How Do You Find The Slope Of A Roof

Just write down the measurements you found.

How do you find the slope of a roof.

For example if the roof slope is 45 then sec 45 1 414213. The slope of your roof is the ratio of vertical distance rise to horizontal distance run. Notes to the table above. Divide the rise by the run.

First enter the value of the rise and choose the unit of measurement from the drop down menu. If asphalt shingles are to be installed on a low slope roof special steps are required to avoid short roof life and roof leaks. As a shortcut the roof slope multiplier for any slope can be determined by finding the square root of rise run 1. For example if you find 4 inches of height with the tape measure at the 12 inch mark on the level your slope is 4 12 or 4 in 12.

Roof slopes are measured in units of twelves. Finally enter the value of the rafter length and. The horizontal distance in the ratio will be 12 while the vertical distance is the measurement you took from the rafters. Another way of stating this is that the roof has a rise of 5 and a run of 12.

For example when a roof has a slope of 5 12 the roof is 5 inches high for every 12 inches long. Using an online calculator. Here are the steps to follow for the roof angle calculator. Find the square root of that result if you know the roof slope in degrees simply find the secant using a scientific calculator.

The slope of your roof is the ratio of the vertical distance or rise of the roof to the horizontal distance or run. There s no need to simplify them. Low slope roofs are from 0 to 3 12 in pitch.
